STEAM-CONDENSER.

SPECIFICATION forming part of Letters Patent No. 355,250, dat ed December 28, 1886.

Application filed February 19, 1886. I Serial No. 192,541. (No model.)

To all whom it may concern:

Be it known that I, TALMADGE BLASS, of Millerton, in the county of D-utchess and State of New York, have invented a new and Improved Steam-Condenser, of which the following is a full, clear, and exact description.

The object of my invention is to provide a condenser for the exhaust-steam of engines that will produce a high vacuum without the {0 use of a pump, and so constructed for regulating the flow of water that the temperature of the hot-well can be kept as desired.

The object is also to render every part of the condenser accessible, and to'prevent clogging by foreign matters in case dirty water is used.

To these ends my invention consists in the condenser constructed as hereinafter described and claimed.

Reference is to be had to the accompanying drawing, forming part of this specification, in which the condenser is shown by a central longitudinal section.

The body of the apparatus consists of a tube,

A, having a flange, a, for coupling to the watersupply pipe, a jacket cast-around pipe A and forming a chamber, B, with a neck and flanges at b for coupling to the exhaust-pipe, and a water-chamber, O, on the end of tube A, hav- 0 ing an elbow, d, for connection to the hot-well,

the end of chamber 0 being closed by a cap,

e, that is formed with a stuffing-box, f. The

end of tube A connecting to chamber 0 flares or spreads outward, and the tube has an an- 3 5 nular slot, y, equal in area to the exhaust-pipe through this flaring portion, which furnishes an outlet from the chamber B formed by the jacket.

D is a cone or tapering plug attached on the 0 end of ascrew-stem, h, passing through a guide,

t, and through the cap 6 and boxf, where the stem is packed by a gland 0n the box. The

plug D is sustained by stem it within the flaring end of tube A, with a space between that 5 forms a channel from the tube to the waterchamber 0, and the angle of the tapering sides of the plug is less than the taper of the tube,

so that the channel or space between is wider at the outer end, It, than at the inlet-point Z.

This difference in size remains in any position to which the plug is adjusted by means of its screw-stem and hand-wheel for varying the size of the channel and flow of water.

This condenserloeing connected, as specified, so as to receive the water in pipe A from an elevated source of supply, the operation is as follows: Thewaterpasses down around the plug D to chamber 0 and by elbow d to the hot-well.

On entering the channel around plug D at the point Z the water has a velocity due tojts head; but at the outlet It by the increase of area a greater flow is allowed, so that a ,vacuum is produced. Then the exhaust-steam, being admitted to the chamberB, passes out of the slot 9 and is condensed by the water, so that a 6 vacuum is produced in the chamber B, which vacuum will be high or low, according to the temperature of the water in the hot-well. I In case the temperature is too high the plug D is tobe moved away from pipe A, thereby allowing a greater flow of water and consequent reduction of temperature in the hotwell, and vice versa. The vacuum'at slot 9, caused by condensation of steam,will be higher than at k or Z, while the vacuum action at k, caused by the enlarged outlet, is greater than at Z. Consequently there is acontinuous draft downward from Z to k, which prevents the water entering at slot 9, and a continuous flow of water is kept up to the outlet at k, regardless of the vacuum at slot 9. \Vhile the flow is thus maintained without necessary assistance from the exhaust-steam, the circulation is practically assisted by the steam, as follows: The steam being exhausted from the engine at or 8 5 above atmospheric pressure down to a high vacuum enters chamber 13 with great velocity and passes out by slot 9 in a jet nearly in the same direction as the flow of water, and is instantly condensed. The particles of water, however, retain their velocity and cause or aid the movement of the injection-water. By removal of cap 6 access is given to the interior of the condenser without disturbing its connections, and byturning back the plug and stem obstructions are allowed to pass the plug freely.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An improved condenser, consisting of 'a tube formed with a flaring end slotted, as shown,

IOU

a chamber around the tube, and a water-chamber below the first-named chamber, and an adjustable tapering plug projecting into the flar- 3. In a condenser of the character described,

the combination, with the pipe A, having a 15 flaring end, of the tapering plug D, having the angle of its tapering sides less than the taper of the tube, whereby the space between the plug and tube will be wider at the outlet end than at the inlet-point, substantially as 20 herein shown and described.
